Robotic Wheelchair Wunkerkind!

Wheelchairs are a dime a dozen but the advent of advance and affordable robotics is truly enabling the disabled. The CARRIER Wheelchair does almost everything – making sure the user is fully independent, capable of traversing any terrain and situation.

The frame is specially shaped to maneuver over a commode. A “trap door” opens so you can use the toilet in a dignified manner. No need for awkward transfers or assisted lifts. Stairs and inclines are a cinch too. A “Galileo Wheel” combines a wheel and track into a single drive with advantages from both. The entire chair even lifts to help you reach higher objects.

Nice concept tho not the first of its kind – the CARRIER seems well thought out and ripe for production. Hey, I’m all for design that can improve quality of life.

The CARRIER was developed as semesterproject at the University of Applied Arts in the Studio Industrial Design 2 Esslinger. (www.creativednaaustria.com)

Nice concept especially stair climbing. I’m physically challenged and am partially mobile. One important feature would be to try and make this light and foldable enough to carry as cabin baggage to enable travel for users.

When I was at uni, I did a wheelchair project and first thing I’ve researched were the types of paralyzed patients and their disabilities, some can use their knees, some can use their back etc… “how can they reach up?”, if you won’t support their knees and L4/L5 spine-bones better while the chair is elevating, well this design will end up on the floor with the person on it.

Possibly the battery is “in” the wheels with the motor if any? Heavy wheels?

Interesting design, however there are several aspects of this design that need to be considered. I realize that this may have been a project, but I’d like to add that design is only one part of product development.

1) Stair Climbing You claim that the gyroscopic system will stabilize the chair, but the stabilization will only work with a forward/backward tilt. Take a second look at the first set of stairs she’s climbing. They’re curved. Because the chair is essentially in a square base. The chair is highly susceptible to rolling on its side (rider included) in such situations.

2) Lift I’m not sure how many paraplegic people you know, but I can tell you that they cannot support themselves with their legs in any way. The “standing lift” is a less than perfect solution to raising the rider. The only way to ensure a useful lift is to lift the individual in the seated position.

3) Redundancy Let me ask you this question: How would the individual move around if the battery went dead while they were out in public? or on the stairs? You might want to consider any type failsafe system.

4) Comfort Any individual that has to use a wheelchair will require using it for an extended period of time, so comfort is key. From my perspective of this design, it looks extremely uncomfortable to sit in. I see very little padding (if at all), a lot of hard plastic or composite materials and the backrest is completely useless unless the individual has full capability to sit upright. Even a paraplegic want to sit back. Don’t take my word for it. Look at the designs for current wheelchairs and see how much thought went into constructing the chair with the user’s comfort in mind.

Suggestions: – Visit a medical supply store that sells electric wheelchairs and ask questions about how certain models work. Compare and contrast. – Sit down and talk to a small set of wheelchair users. Find out the problems with the wheelchair directly from the users. – Run your design by someone with a background in engineering (mechanical and/or electrical) to discover unforeseen problems.

Again, this is a promising design and I think you all have some very creative designs.

(Please keep in mind that I am in no way an expert in wheelchair design. Thank you for your understanding.)

It is a very interensting design, specially the stairclimbing. I would like to know for what kind of handiccapped people is this design, where is the battery and where are the giroscopes. Maybe, its a wheelchair for a person who is temporally disabled and this concept will help in his rehabilitation. Isnt it?

There are many types of mobility scooters that are available today. They are designed to make it easier for those who have difficulty walking to go about their everyday tasks. Not being able to walk for an extended period of time can really hinder a person’s mobility and can force you to rely on others to help you go shopping and to the store.

Especially in objective driven match types like sabotage, there’s always a foolish group of players who rush right at the enemy. You should avoid placing the antenna close to any object which can create a signal blockage and even result an accidental damage. Camouflage basically means trying to blend in with the color you chose when selecting your gun

I’m truly enjoying the design and layout of your blog. It’s a very easy on the eyes which makes it much more enjoyable for me to come here and visit more often. Did you hire out a designer to create your theme? Excellent work!

Hi there! This blog post couldn’t be written any better! Going through this post reminds me of my previous roommate! He constantly kept talking about this. I most certainly will send this article to him.

I love many things about this chair. I am paralyzed (L1) I would need a softly padded seat and a little better back rest. To stand it looks like there are knee, thigh, hip and waist restraints but you would also need something behind each heel and a padded chest restraint to prevent falling forward. How is it in the snow, mud, in the woods going over rocks and tree roots, at the beach, etc. Is it ok in the rain or getting wet, are things sealed? How fast does it go? How steep a hill can it take? How heavy is it? How far can it go on its battery? Is there a backup? Can I lift it or pull into a car by myself? How much is it? If someone decides to make this, I want to know about it.
